USI Numbers – What are they? What do they do?

Every year millions of people across Australia undertake nationally recognised training in the VET sector. Previously it was difficult to keep track of who did what courses, when they completed them, and whether or not they passed. With this in mind the federal government mandated that RTO’s report all instances of nationally recognised training to one centralised hub.

Through this one central location RTO’s advise when a learner completed a course, whether or not a learner has passed a course and attained the particular qualification and many other details.


The Unique Student Identifier (USI) system was put in place from the 1st of January 2015. This means that any people who have undertaken nationally recognised training since this date will have their completion of those courses recorded on the USI system.*

You are able to download / print off a transcript of all completed courses since 1 January 2015, with there no longer being any doubt as to someone’s completion in a course. This can be very helpful when applying for other courses, where there are pre-requisite units of competency or qualifications which are required prior to attendance. It also greatly helps with employment where you need to be able to prove what courses you have completed and what qualifications you have attained.

Unfortunately the system is not retrospective, therefore any training that was completed prior to 1 January 2015 is not included on your transcript.


For all of AATC’s courses, including our traffic control and traffic management courses, we will need to be able to access, verify and/or create your USI number (reference number made up of a mix of 10 numbers and letters).

Note you will keep the one (1) USI number with you for the rest of your life, there is not a different USI number allocated for each instance of training.

For more information, including some helpful videos, visit the USI website here.


*Note: there are some people who may qualify for an exemption to this.
